Using an Element Width placeholder in a custom GUI causes the value to fail to parse and causes to spam the game log with parsing errors.
When used in vanilla GUIs, Element Width works fine.

To Reproduce

Steps to reproduce the behavior (e.g.):

1. Create a custom GUI and a custom layout for the aforementioned Custom GUI.
2. Add a new Button.
3. Advanced Positioning -> X position -> insert:
   {"placeholder":"calc","values":{"expression":"{"placeholder":"guiwidth"} / 2 - {"placeholder":"elementwidth","values":{"id":"*your_button_ID_here*"}} / 2","decimal":"false"}}
   (this should center the button)
4. Notice that in the editor everything is fine, but in the actual menu the button is aligned to the left and the log is flooded with parsing errors.

Expected behavior

The button should be centered in the actual GUI.
